Cotton has the tensile strength of cotton.

It's not close to silk.

Real bamboo fiber is much stronger and tougher than cotton (while most "bamboo" in the market is actually rayon).

Silk beats bamboo.

You can compare anything... as long as you can come up with a valid method of testing. Sometimes that's pretty hard, which is why there ARE testing standards for things common in commerce.

However, in spite of your claim it does, the tensile strength of cotton fiber just isn't mentioned on that page that I gave you the link to. I was aware of that when I gave you the link. Carbon fiber is different than cotton fiber, even though cotton fiber is largely made of carbon... so perhaps that's the source of confusion ?

The most impressive fiber I've seen... was one that was so tiny you couldn't even see it... but it was still strong enough that when you were holding it... you couldn't break it just by pulling your hands apart... without adding a "snapping" motion. It was flexible, too, to a point, but, it was pretty stiff and brittle.

You'll generally have a much harder time breaking a silk thread than a cotton thread... even if the cotton thread is much thicker.

Silk is stronger.

Artificially spun silk... will be stronger than naturally spun silk... mostly because it will be composed of fibers that are more uniformly made... and the process is both better able to be controlled, and capable of being improved... when you're just not going to have very much luck trying to teach the worms to do better than they do now...
